Global Analysis of KOI-977: Spectroscopy, Asteroseismology, and Phase-curve Analysis
Teruyuki Hirano, Kento Masuda, Bun'ei Sato +5
We present a global analysis of KOI-977, one of the planet host candidates detected by {\it Kepler}. Kepler Input Catalog (KIC) reports that KOI-977 is a red giant, for which few c…
Determination of Three-dimensional Spin-orbit Angle with Joint Analysis of Asteroseismology, Transit Lightcurve, and the Rossiter-McLaughlin Effect: Cases of HAT-P-7 and Kepler-25
O. Benomar, K. Masuda, H. Shibahashi +1
We develop a detailed methodology of determining three-dimensionally the angle between the stellar spin and the planetary orbit axis vectors, , for transiting planetary systems.…
Very Low-Density Planets around Kepler-51 Revealed with Transit Timing Variations and an Anomaly Similar to a Planet-Planet Eclipse Event
Kento Masuda
We present an analysis of the transit timing variations (TTVs) in the multi-transiting planetary system around Kepler-51 (KOI-620). This system consists of two confirmed transiting…
Tidal evolution of the spin-orbit angle in exoplanetary systems
Yuxin Xue, Yasushi Suto, Atsushi Taruya +3
The angle between the stellar spin and the planetary orbit axes (spin-orbit angle) is supposed to carry valuable information on the initial condition of the planet formation and th…
